AMD Ryzen 9 7950X3D Overclocked to 5900 MHz With ROG Crosshair X670E Extreme | SkatterBencher #56

hello and welcome back in today's video I'm overclocking the AMD ryzen 9 7950x3d CPU all the way up to 5.9 gigahertz using the Asus Rog Crosshair x670e Xtreme motherboard and EK Quantum custom Loop water cooling before we get going I want to say a quick thank you to the folks at AMD that decided to unlock the x3d for overclocking that's a different approach than with the first generation of ryzen xod CPUs and I like that that doesn't mean that the overclocking is fully supported or that it's as easy to overclock the x3d CPUs as it is to overclock the regular ryzen 7000 CPUs but the intent is there and and I like that anyway we have a lot to go through in this video so let's get started the AMD ryzen 9 7950 x3d CPU is part of the third wave of ryzen 7000 Zen 4 am5 desktop processors the first wave of Zen for ryzen 7000 processors launched on August 29 2022 during an AMD live stream at launch there were four x skus available ranging from the 6 core 105 watt ryzen 5 7600x to the 16 core 170 watt ryzen 9 7950x the second wave of ryzen 7000 processors launched on January 4 2023 during amd's CES 2023 keynote this wave consisted of three non-x skus available a few days after the announcement the skus arranged from the 6 core 65 watt ryzen 5 7600 to the 12 core 65 watt ryzen 9 7 900. at the CES 2023 keynote AMD also announced the third wave of ryzen 7000 processors which consist of exclusively X 3D variants with 3D V cache the lineup consists of three skus ranging from the 120 watt 8 core 7800 X 3D to the 16 core 7950x3d the ryzen 7 7800 x3d is a direct successor of the ryzen 7 5800 x3d amd's first consumer CPU with 3D V cache despite being locked for overclocking we overclocked the ryzen 7 5800x3d in scatterbanger Number 39. the 7950 x3d and the 7900 x3d are the first dual CCD Horizon x3d enabled processors I won't say too much about the technical aspect of 3D V cache has plenty of other media will cover that part of the x3d story but long story short AMD has 3D stacked additional L3 cache on top of the CCD to expand the ondite cache capacity that in theory should help improve the performance in latency sensitive workloads we'll discuss the vcache and its impact on performance later in this video the ryzen 9 7950x3d has two eight core ccds totaling 16 cores with 32 threads one of those ccds has vcash while the other doesn't the base frequency is 4.2 gigahertz and the maximum listed boost frequency is 5.7 gigahertz the TDP is 120 Watt and the PPT is 162 watt in this video we will cover three overclocking strategy first we rely on AMD pbo2 and Expo performance boost Technologies second we tune Precision boost overdrive 2 with curve Optimizer third we tuned Precision boost overdrive 2 with a synchronous e-clock however before we get going with the overclocking let's have a quick look at the hardware and the benchmarks that we'll be using in this guide the system we are using for this overclocking guide consists of the following Hardware I explain how I use the almolab's products in scatterbanger number 34. to make a long story short I connect the EFC to the evc2 device and that allows me to monitor the ambient temperature water temperature and fan duty cycle I also include these measurements in my Prime 95 stability test results I also use the almolabs ESC to map the radiator fan curve to the water temperature without going into too many details I've attached an external temperature sensor from the water in the loop to the EFC then I use the low high setting to map the fan curve from 25 to 40 degrees water temperature I use this config iteration for all overclocking strategies the main takeaway from this configuration is that it gives us a good indicator of whether the cooling solution is saturated we use Windows 11 in the following Benchmark applications to measure performance and ensure system stability I added geekbench 6 right before finalizing the script as it had just launched a few days ago I will phase out geekbench 5 and replace it with geekbench 6 in future scatterbanger guides before starting overclocking of course we must check the performance at default settings the default parameters for the Precision boost to algorithm for this 7950x3d CPU are as follows these values don't tell the whole picture of how Precision boost works on the 7000 X 3D processors I'll get back to that later in the video here's the Benchmark performance at stock here are the 3dmark CPU profile scores at stock when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4255 megahertz with 0.9 volts the average CPU temperature is 66.8 degrees Celsius the ambient and water temperature is 23.2 and 30.6 degrees Celsius the average CPU package power is 121.6 Watts when running prime95 small ffts with AVX disabled the average CPU effective clock is 4500 and 53 megahertz with 0.959 volts the average CPU temperature is 81.5 degrees Celsius the ambient and water temperature is 23.2 and 30.8 degrees Celsius and the average CPU package power is 134.2 Watts now let us try our first overclocking strategy but before that make sure to locate the clear CMOS button pressing the clear CMOS button will reset all your bias settings to default which is helpful if you want to start your bios configuration from scratch in our first overclocking strategy we will leverage AMD exclusive features like Precision boost overdrive 2 and extended profiles for overclocking however before we start talking about Precision boost overdrive let's return to the Precision boost technology topic I spoke at length about the Precision boost technology in my rafale launch video in order to fully understand what I'm about to explain about overclocking the ryzen 9 7950 x3d it's good to have a thorough understanding of how Precision boost Works Precision boost 2 is an automatic performance maximizing technology available in all AMD ryzen processors since the 2018 Horizon 2000 Series this technology improves system performance by dynamically increasing your processor clock speeds Beyond stock depending on many factors including temperature power consumption current draw and the number of active cores the fundamental building block of the Precision boost technology is the SMU or system management unit each chip on your Rafael CPU has an SMU meaning there are three smus on a ryzen 9 7950x3d CPU one of those smu's functions as Master SMU while the others work as slave smus typically the SMU and the io die would be the master SMU all smus are connected using a low bandwidth control bus called SCF or scalable control fabric the SMU has a range of capabilities including most importantly the ability to manage the CPU performance within the infrastructure constraints the infrastructure restricts the maximum operating limits on various metrics including power draw temperature and voltage the primary function of the smus is to capture the measurement data related to the infrastructure limits then prepare that data to be sent to the master SMU the master smu's primary function is to analyze the package-wide measurement data and determine the actions needed for Performance Management each infrastructure limit has its algorithm and is managed independently by the master SMU to determine the infrastructure limited frequency the firmware then selects the most constraining limit as the global frequency limit then either of two things can happen either the frequency exceeds the limits or it doesn't if the frequency exceeds the limit then the frequency will be reduced if the frequency doesn't exceed the limit then the frequency will be increased either way the master SMU passes the frequency change request to the slave SMU and then each slave SMU applies the frequency changes to the CPU cores of the local die the frequency changes are coordinated with the global voltage plane by the master SMU now comes the part that is important for ryzen 7000x3d overclocking every slave can make independent decisions based on local conditions so it can apply lower frequencies than the frequency requested by the master SMU if the on-dike conditions require so for example one CCX may run at a lower frequency in all core workloads additionally when dldo is enabled each SMU can independently adjust the voltage for each core within the CCX the Precision boost algorithm has many infrastructure limiters some of which are even exposed to the end user while all of these limiters are present on ryzen 7000 CPUs it doesn't mean that they're all active or configured furthermore the infrastructure limiters can differ CCD to CCD for example the ccd0 the one with the V cash is severely more restricted than our ccd1 the one without the vcache here's a list of the Precision boost limiters we're aware of I discussed these at length in my Raphael overclocking what's new launch video so I'll only discuss the relevant ones for the ryzen 9 7950x3d the main limiter constraining the ryzen 9 7950x3d is the voltage limit I will refer to the vcash ccds ccd0 and the non-v-cash ccd-s ccd1 as you can see from the table the vid limit for both ryzen 7000x3d ccds is lower than that of a regular 7950x processor furthermore at 1.2 volt the voltage limit for CCD 0 is significantly lower than 4 ccd1 Rapha only has one vddcr voltage rail powering the CPU cores inside the ccds via the vddcr CPU voltage Rail and the cache via the vdd CR vddm rail when any core and CC 0 is active it will also restrict the maximum voltage for the course in ccd1 that will also constrain its operating frequency note that the vid limits are the absolute limits at zero load as you increase the load on a CCD the Precision boost algorithm will further reduce the maximum allowed voltage the maximum voltage in an all-core workload with active cores and ccd0 is a mere one volt that's similar to the maximum voltage for a stock non-x ryzen 7000 processor the maximum voltage in an all-core workload for ccd1 is a 1.2 volt another limit constraining the ryzen 9 7950x3d is the f-max limit unsurprisingly the CCD with vcache cannot run at equivalent speeds to the non-v-cache CCD since the L3 cache operates at the same frequency we also saw this with the ryzen 7 5800 x3d e which had a 200 megahertz lower maximum boost clock than the ryzen 7 5800x on the ryzen 9 7950 x3d ccd0 has an f-max limit of 5.25 gigahertz and ccd1 has an fmac limit of 5.75 gigahertz fortunately every CCX has its own PLL so in theory we'd be able to run all the cores in ccd0 at 5.25 gigahertz and all the cores in ccd1 at 5.75 gigahertz at the same time however in the real world that's not going to happen because the ccds share the same voltage Rail and will therefore always run the course at the same voltage if only dldo was available on am5 there's one last point that I want to discuss regarding the 3D V cache performance obviously each CCD has its own strength ccd0 has more cash but a lower frequency and ccd1 has a high a frequency but less cash obviously you want to run your application on the CCD that provides you with the most Advantage with the highest performance so how does AMD manage that long story short through drivers to make a short story slightly longer you can choose how to prioritize the ccds in the Bios you can let the system drivers take control and prioritize the CCD with extra cash or the CCD with the additional frequency Asus Rog has also implemented a custom prioritization algorithm using its core Flex feature you can load the x3d core Flex gaming preset to check its impact on system performance the core Flex algorithm is a little complicated but it comes down to this there are three states level one level two and level three levels 1 and 3 prioritize ccd1 and level 2 prioritizes ccd0 two threshold values triggered the states level 1 and level 2 threshold the profile's condition to check is the core current and the threshold values are 20 and 50 amps respectively if the core current is below 20 amps level 1 state is active if the core current is between 20 and 50 amps level 2 state is active and if the core current exceeds 50 amps level 3 state is active an active State doesn't mean there's core re-prioritization just yet in addition to the core current check there's also a memory activity threshold CCD priority switching will only occur if the memory activity exceeds the threshold you can interpret the algorithm as follows if the system is Idle there's no CCD reprioritization in case of a memory intensive workload that doesn't use more than 8 cores coreflex prioritizes ccd0 with vcache to benefit from the extra L3 cash in case of a memory intensive workload that utilizes more than eight cores coreflex prioritizes ccd1 to benefit from the higher average CPU frequency it's not easy to get a good feeling of a want approach to CCD prioritization gives you the best performance so I suggest that you just try it on your own system and see what works best it would be remiss of me to not at the very least mention the lesser-known Precision boost C State limiter I made a video on this specific topic a while back so I won't go into the details here but it's a pertinent topic when it comes to ryzen Performance Tuning long story short since agisa1003 did Precision boost c-state boost limiter prevents zen-4 CPUs from boosting over 5.5 gigahertz when more than four cores are active however this C State limiter appears not present on agisa 1005 which came with this bios I've not been able to confirm this with a regular xsku so be on the lookout for Forum posts or media reports that includes our shallow dive in the Precision boost to technology there is a lot more to the clocking and the voltage of ryzen 7000 CPUs but I'll refer you to my Raphael launch video for that now it's time to get into the overclocking of the 7950 x3d processor with the launch of Zen 3 AMD introduced an improved version of precision boost overdrive they call this Precision boost overdrive 2. the Precision boost overdrive 2 toolkit still provides us with the tools to manually tune the parameters that are governing the Precision boost algorithm Precision boost overdrive 2 builds on the PBO implementation of Zen 2. In addition to the platform overclocking knobs from Zen plus PPT TDC and EDC and processor overclocking knobs from Zen 2 boost override and scalar Precision boost overdrive 2 introduces curve Optimizer there are essentially three levels of AMD Precision boost overdrive amd's stock values which can be set by disabling PBO the motherboard vendor values which are programmed into the BIOS to match the motherboard vrm specification and can be set by enabling PBO and custom values which the end user can program in this overclocking strategy we're just enabling Precision boost overdrive whereas in the next strategies we'll also look into tuning the various parameters we rely on the motherboard's pre-programmed PBO parameters by enabling Precision boost overdrive we find that the following values have changed for previous generation ryzen CPUs increasing the platform boost parameters substantially impacted the performance especially for the higher core counts tpus for a ryzen 7000 X Series CPUs however amd's default platform parameters were relatively unconstraining for the x3d series CPUs however it seems the limiters are again slightly more constraining during a prime 95 non-avx workload TDC and EDC are close to or at the limit Expo stands for AMD extended profiles for overclocking it's an AMD technology that enables ubiquitous memory overclocking profiles for AMD platforms supporting ddr5 memory Expo allows memory vendors such as g-skill to program higher performance settings onto the memory sticks if your motherboard supports Expo you can enable higher performance with the click of a single button so it saves you from a lot of manual configuration while our memory kit is rated at ddr5 6400 I couldn't quite make it work stably on this system so I had to settle for ddr5 6000 instead upon entering the BIOS go to the extreme tweaker menu set AI overclock tuner to Expo 1. set a memory frequency to ddr56000 enter the Precision boost overdrive submenu set Precision boost overdrive to enabled then save and exit the BIOS we rerun the benchmarks and check the performance increase compared to the default operation as expected enabling Precision boost overdrive does little to improve the system's performance after all the CPU is primarily limited by the operating voltage not by any platform power parameter years thanks to enabling Expo we do get a performance Improvement of Plus 8.17 in AI benchmark when running prime95 small ffts with AVX 512 enabled the average CPU effective clock is 4261 megahertz with 0.9 volts the average CPU temperature is 67.6 degrees Celsius the ambient and water temperature is 25 and 32.1 degrees Celsius the average CPU package power is 132 Watts when running prime95 small ffts with AVX disabled the average CPU effective clock is 4540 megahertz with 0.958 volts the average CPU temperature is 82.6 degrees Celsius the ambient and water temperature is 25.1 and 32.6 degrees Celsius and the average CPU package power is 143.9 watts in our second overclocking strategy we will make the use of the fmax Boost override and curve Optimizer tools included in the Precision boost overdrive 2 toolkit if Max is one of the Precision boost limiters constraining the CPU performance essentially it determines the absolute maximum CPU frequency that any of your CPU cores are allowed to run boost clock override or fmax override is one of the overclocker tools available in the pbo2 toolkit it allows the user to overwrite the arbitrary clock frequency limit between -1000 megahertz and plus 200 megahertz in steps of 25 megahertz it's available for both the CPU core clock and if present the graphics core clock we need to make two important notes about boost clock override the override only adjusts the upper ceiling of the frequency and doesn't act as a frequency offset ultimately that Precision boost 2 algorithm still determines the actual operating frequency ccd0 the one with v cache appears locked from increasing the f-max so while setting a negative boost override to lower the F Max Works setting a positive boost override to increase the F Max doesn't work the F Max remains at 5250 megahertz as I mentioned earlier in this video curve Optimizer is an important new feature in the Precision boost overdrive 2 overclockers toolkit curve Optimizer allows the end user to fine-tune the cpu's vft curve vft stands for voltage frequency temperature curve and it's essentially a table that determines for each core in your CPU what voltage to run for a specific frequency and temperature the higher your frequency or the higher your operating temperature the higher the voltage you'll need curve Optimizer adjust the vft curve by offsetting the voltages of the factory fused vft curve by setting a positive Offset you increase the voltage Point conversely you decrease the voltage Point by setting a negative offset the traditional approach for AMD ryzen CPU overclocking is to use a negative curve optimizer two things happen when you do that first you tell the CPU that it needs less voltage for a given frequency and as a consequence at a given voltage it can apply a higher frequency second the CPU temperature will be lower because you use a less voltage at a given frequency that extra thermal Headroom will also encourage the Precision boost algorithm to Target higher voltages and frequencies as I mentioned already curve Optimizer is available on a per core basis and that gives us a tangible real-world benefit as it allows us to push some of the better cores a lot higher than the other weaker cores the manual tuning process with curve Optimizer can become quite convoluted because it spans a wide range of scenarios going from single threaded light workloads all the way to all core heavy workloads the tuning process that I followed for this CPU was as follows in my case I used a per core curve Optimizer ranging from -40 on car 6 to -15 On Core 2 and an fmax boost override of plus 150 megahertz I will show you the BIOS configuration in a minute but first please note that the per core curve Optimizer settings are CPU specific and the optimal values of your CPU May differ substantially the following table shows the Boost profile for this specific CPU we can make a couple of interesting observations at stock the Boost curve shows several cores running higher than the advertised boost frequency of 5.7 gigahertz that's not unexpected as we know the fused f-max is 5.75 gigahertz but it's still nice to see some cores over delivering on their promise furthermore we can also see that several vcash cores run at their f-max of 5250 megahertz it's also interesting to see the average frequency across an increasing number of active threads during the shamina Boost curve workload it nicely shows how the average frequency decreases when the first eight ccd1 cores are loaded then 8 ccd0 cores then the 8 smt ccd1 cores and finally the 8 smt ccd0 course after curve optimizing we see a substantial frequency uplift across the board some cores almost hit the new f-max ceiling of 5.9 gigahertz and all vcash cores hit the 5.25 gigahertz F Max the average frequency under load also increased by roughly 200 megahertz across the board upon entering the BIOS go to the extreme tweaker menu set AI overclock tuner to Expo 1. set memory frequency to ddr5 6000 enter the Precision boost overdrive submenu set Precision boost overdrive to enabled set CPU boost clock override to enabled positive set max CPU boost clock override to 150. enter the curve optimizer submenu set curve Optimizer to per core for every core set curve Optimizer signed to negative for course 0 5 9 and 12 set curve Optimizer magnitude to 30. for course 1 3 8 10 and 11 set curve Optimizer magnitude to 20. for Core 2 set curve Optimizer magnitude to 15. for course 4 14 and 15 cent curve Optimizer magnitude to 35. for core 6 set curve Optimizer magnitude to 40. for course 7 and 13 set curve Optimizer Magna 2 to 35 then save and exit the BIOS we re-ran the benchmarks and check the performance increase compared to the default operation while the performance uplift after curve optimizing is not earth shattering it's nice to see we achieve better performance across the board we see the highest performance Improvement of plus 10.54 percent in AI Benchmark when running prime95 small ffts with AVX 512 enabled the average CPU effect of clock is 4432 megahertz with 0.885 volts the average CPU temperature is 67.6 degrees Celsius the ambient and water temperature is 23.4 and 30.8 degrees Celsius the average CPU package power is 137.7 Watts when running prime95 small ffts with AVX disabled the average CPU effective clock is 4732mhz Hertz with 0.945 volts the average CPU temperature is 82.5 degrees Celsius the ambient and water temperature is 23.7 and 31.9 degrees Celsius the average CPU package power is 150 watts in our final overclocking strategy we will leverage e-clock mode e-clock stands for external clock and does exactly what the term suggests it allows us to use an external clock generator this function was previously available on Horizon 2000 Pinnacle Ridge CPUs but then was later removed until the ryzen 7000 CPUs it's back the standard Raphael platform has a 48 megahertz Crystal input to the integrated CG PLL clock generator the cgpl then generates a 48 megahertz clock 40 USB PLL and a 100 megahertz reference clock 40 fch which contains the cclk PLL for the CPU cores and several SOC plls in addition to the standard internal cgpl Raphael supports up to two external clock modes they're called e-clock zero mode and e-clock one mode and e-clock zero mode and external 100 megahertz reference clock is used for both the CPU and SOC plls in other words it's a reference clock that affects the CPU core clocks as well as the pcie and SATA clocks and e-clock one mode there are two distinct external 100 megahertz reference clocks one clock provides the 100 megahertz input for the CPU PLL and another provides the 100 megahertz reference clock for the soc plls in previous scatterbancher guides the one before Horizon 7000 I refer to using the reference clock as supercharging PBO unlike previous platforms using the reference clock for overclocking Horizon 7000 CPU is actually very well supported and it provides us with a real viable path for performance tuning the overclocking strategy with e-clock is the polar opposite of what we're used to with ryzen CPUs OC strategy number two shows that ryzen overclocking is typically done with a negative curve Optimizer that pushes the Precision boost algorithm to reach higher boost frequencies with e-clock we still build on the fact refused vft curve but adjust the frequency by adjusting the reference clock for example if there's a vft 0.45 gigahertz at 1.15 volt at 50 degrees Celsius with an e-clock of 105 megahertz the actual point will be 5250 megahertz at 1.15 volt at 50 degrees Celsius the default voltage for this vfd.1 suffice for its stable operation so counter-intuitively we use a positive curve Optimizer to increase the voltages of the vfd point one more critical point e-clock also affects the maximum frequency ceiling with an e-clock of 105 megahertz the newly programmed F Max for the 7950 x3d is 5750 megahertz multiplied by 1.05 equaling 6038 megahertz that's way too high for this CPU with non-x3d CPUs we could use a negative fmax boost override to fix this however it's a little more complicated since the ccds in the 7950x3d have a different default F Max so reducing the F Max for ccd1 also impacts ccd0 the manual tuning process with e-clock can become quite convoluted because it spans a wide range of scenarios going from light single threaded workloads to heavy all core workloads the tuning process that I followed for this CPU was as follows in my case I used an e-clock of 104 megahertz and a per core curve Optimizer ranging from zero on core 7 to plus 25 on core 2. I will show you the BIOS configuration in a minute but first please note that these settings especially the curve Optimizer ones are CPU specific and the optimal values for your CPU May differ substantially the following table shows the Boost profile for this specific CPU we can make a couple of interesting observations we can use e-clock tuning to increase the frequency of the cores in the locked 3D vcache CCD it also helps us to improve the frequency in the other CCD though not much more than what we got from curve optimizing while tuning with e-clock provides generally speaking higher boost frequencies than tuning exclusively with curve Optimizer the maximum boost frequencies are not that far apart overall the e-clock strategy typically provides an Avenue to slightly higher frequencies at the cost of slightly higher voltages while this offers better performance in light workloads the higher voltages will push the CPU quicker to the thermal limit thus in heavy workloads strictly using the curve Optimizer tool for undervolting yields slightly better results upon entering the BIOS go to the extreme tweaker menu set AI overclock tuner to Expo 1. set e-clock mode to asynchronous mode set bclk2 frequency to 104. set memory frequency to ddr56000 enter the Precision boost overdrive submenu set the Precision boost overdrive to enabled enter the curve Optimizer Sub menu set curve Optimizer to per core for every core set curve Optimizer assigned to positive for course zero four five eight and ten set curve Optimizer magnitude to 10. for Core 1 set curve Optimizer magnitude to 20. for chord 2 set curve Optimizer magnitude to 25. for chord 3 set curve Optimizer magnitude to 15. for course 6 9 11 12 and 13 set curve Optimizer magnitude to 5. for course 7 14 and 15 set curve Optimizer magnitude to 0 then save and exit the BIOS we rerun the benchmarks and check the performance increase compared to the default operation while we can increase the performance over stock it's clear that the need for using a positive curve Optimizer is impacting the overall performance as expected we see the most significant Improvement in single threaded benchmarks especially those running on the vcash CCD however in multi-threaded benchmarks we see less Improvement than with curve optimizing due to the need for using the positive curve Optimizer we get the highest performance Improvement of plus 9.63 percent in geekbench 6 multi when running prime95 small ffts with AVX 512 enabled the average CPU effect of clock is 4307 megahertz with 0.905 volts the average CP temperature is 68.2 degrees Celsius the ambient and water temperature is 22.5 and 31.1 degrees Celsius the average CPU package power is 140.8 Watts when running Prime 95 small ffts with AVX disabled the average CPU effective clock is 4592 megahertz with 0.963 volts the average CPU temperature is 83.3 degrees Celsius the ambient and water temperature is 22.3 and 31.3 degrees Celsius the average CPU package power is 152.1 Watts all right let's wrap this up I want to kick things off by repeating what I said at the very beginning of the video and that's by thanking the folks at AMD that decided to enable overclocking for this generation of x3d processors overclocking today is very different than what it was 15 years ago as nowadays it actually requires a substantial effort to enable support and validate the overclocking toolkit I just want to say that I really appreciate that AMD went through this effort that's not to say that overclocking the 7000 x3d CPUs is going to be very easy or is even fully supported manual overclocking is still not available and the CCD with the V cash is severely restricted in terms of Maximum voltage as well as maximum frequency but you get the curve Optimizer so you can tweak where the negative curve offset and get maybe a little bit more frequency and if you really want to you can also use a synchronous e-clock to push up the frequency in your vcash CCD so those options are available anyway that's it for me today I want to thank you for watching and I want to thank the patrons for the support as per usual I will have a written version of this video up on my blog if you want to read through the bio settings or check my performance results as per usual if you have any questions drop them in the comment section below and see you next time thank you

i'm surprised i've never heard of this guy before, seems to really know his stuff and the presentation is excellent.

[u/bubblesort33]

Aren't these not out until tomorrow?

[u/pluto7443]

Is he only using PBO modifications? And which CCD?
